= SOLE-'LEVELING- MACHINE,

Applicationfiled- November 17, 19.11. SeriaLNo; 660,842.,

To all whom it may concern Be it known that I, WARREN FRASIER, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful improvements in Sole- Leveling Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention relates .to sole leveling machines, and-moreparticularly to that class of leveling machines which comprise aleveling roll and a shoe supportingjack relatively movable to changetherelative longitudinal position of the leveling roll and jack.

hen leveling the soles of turn shoes, the leveling roll is rotated toimpart a rubbing action to the surface of the sole in addition to theleveling pressure which is exerted by the roll. As the leveling roll isrotated con-. tinuously in one direction at a higher speed than thetravel of the jack, the rubbing action always takes placein the, samedirection irrespective of the direction of movement of the jack, andwhen operating upon the lighter grades of shoes, this rubbing movementoften displaces the sole sufliciently to distort the shoe and render itunsalable.

One object, of the present invention is to equalize the draw upon thesoleand enable all grades of shoes to be properly leveled withoutdisplacing the sole from its proper position relative to the upper orotherwise distorting the shoe.

With this object in view, one feature of the invention contemplates theprovision of a shoe supporting jack, a cooperating leveling roll, meansfor varying the relative lon gitudinal position of the roll and jack,and

mechanism operatively connected with the roll and acting automaticallyto cause the roll to rub different portions of the sole in oppositedirections while maintaining a con stant direction of movement of thejack. Broadly considered, this feature of the invention is'not limitedto the employment of a continuously rotated roll, but contemplates theprovision of a roll with any mechanism operatively connected thereto forcausing the roll to rub the sole of a shoe.

Machines of this character are also employed for leveling very lightshoes Worn by entire surface of. the sole, including the heel 7 portionor heel seat; l/Vhen employing eX- Specification of LettersPa-tent.Patentefl Feb; 15,1916, 1 i

isting machines of this type for this vpurpose, the edge of the sole.a't'the heel seat is pulled awayfromithe upper andcounter when theleveling roll rides onto the shoe at this point. In order to avoidthis,the-machines are often arranged to stop'the travel of the ack before theroll has reached the rear edge of the heel seat. This mode of operation,however, is obviously objectionable, as abridge is formed upon themargin of the sole which is not leveled and stands up from the remainingsurface of the sole:

able the entire surface of the sole, including the heel seat, .to beproperly leveled without marring the edges of the sole at either the oheel or toe, or straining the fastenings be;

tween the sole and upper of etheshoe at these,

points.

.With this object in view, a further feature of the invention consistsinthe combination, -with .a shoe supporting jack and leveling roll, ofmechanism for rotating the. rollin the direction of travel oftl ie jackas the roll is moved-into engagement with the shoe at the toe and heelrespectively. e V W Still further features of the invention A furtherobject of the invention'is .to en comprise certain novelfeatures ofconstrue- 1 ';tion, combinations and arrangements. of

parts hereinafter described and, claimed, the advantages. of which willbe apparent to those skilled in the art frorn the following description.

The severalfeatures of the invention will be clearly understood from aninspection of" the accompanying drawings, in which Figure 1 represents aside elevation of levelingmachine embodying the several fea-,

tures of the invention in their preferred: form; Figs is a view in sideelevation look} ing at the opposite side 'of the leveling ma chine fromFig. 1; Fig. 3is .a top plan' view ofzthejleveling machine; Fig. 4 is adetail showinga side elevation of a portion of the operating mechanismfor the leveling roll; Fig. 5 is a detail showing an end elevation of aportion of the mechanism for operating the roll; Fig. 6 is a detailview-illustrating the mechanism shown in Fig. 5, looking'atthe same fromone side; Figst'7 'a'nd '8 are details of the operating mechanism; Fig.9 is a section upon the line 99 of Fig. 3; and- Fig. 10 is a view,partly diagrammatic, "illustrating the action of the leveling roll *uponthe sole of a shoe.

Certain parts of the machine are similar in theirconstruction and modeof operation to the machine shown and described in the patent to AndrewEppler; No. 1,00%,155, dated September 26, 1911, and will be onlybriefly described herein in consequence thereof.

The sole leveling roll is indicated at 1 and is lournaled in the forwardend of a frame 2 which-is pivotally mounted at its rear end in the upperrear portion of the machine frame 3. The shoe is supported upon asuitable jack 1 which is pivotally mountedat 5 on the 'jack' carryingframe 6. The

shoe supporting jack 4 is rock'edlaterally by the operator to vary therelative lateral inclination of the leveling roll and jack and at thesame time is moved back and forth beneath the leveling roll to effect arelative longitudinal movementof the leveling roll and jack. To this endthe jack carrying frame 6 is pivotally mounted in the machine frame at7, and is oscillated by a connecting rod 8 and crank9. The crank 9 ismounted upon a crank shaft 10 to which a partial rotation is impartedperiodically in opposite directions by a large friction disk 11 engagedalternately by a pair of small friction disks locked to the pulleys 12and 13 respectively. A rocker frame 1 1 is pivotally connected to themachine frame at 15 and is operated to throw either of the smallfrictiondisks into engagement with the friction disk 11 by a handle 16conveniently accessible to the operator. A continuous rotation isimparted to the pulleys 12 and 13 froma drive pulley 17 through a beltconnection 18. To prevent an overthrow of the jack supporting frame incase the operator does not move the handle 16 at the proper time anautomatic stop mechanism is pro ,vided which is indicated at 19. Theroll 1 is yieldingly held against the sole of the shoe by a treadle 22which is connected to the roll supporting frame 2 through a spring 23.The dead weight of the leveling 7 roll and operating mechanism issupported by a spring 2% connecting the rear end of the supporting frame2 with the machine frame 3. The leveling roll, is continuously rotatedduring the operation of the machine oya drive pulley 25 supported in theupper rear portion of the machine frame and operated from the main drivepulley 26 through a suitable belt connection 27.

These machines are employed principally for leveling the soles of turnshoes and in addition to the downward pressure which serves to bed thesole'upon the last, a rubbing action is exerted upon. thesurface of thesolewhich smooths out the; surfaceand imparts the desired finish to thesame:v

When this rubbing action is always directed toward the same end of theshoe, it tends to distort the lighter grades of shoes unduly and inaddition the margin of the sole at. the opposite end of the shoe isrubbed up when. the roll rides upon the shoe at this point. In thepresent lnvention the three-- tion of rotation of the roll is reversedwith-v out changing the direction of movement of the jack, and thisreversal of the roll takes place approximately at the ball. line oftheshoe, thus rubbing the shankand ball pore tions of the sole in-oppositedirections. In

addition, the driving mechanism of the roll? is so arranged that whenthe roll rides on. the toe and heel. of the shoe respectively, thedirection of rotation of the roll in each 111- stance corresponds withthe direction, of movement of the-jack. In the simplest and mosteilicient form of the invention which has as yet been devised, this isaccomplished by providing two driving members for the leveling rollwhich are continuously rotated 1n opposite d1rect1ons,,and automaticmeans for operatively connecting I the roll with eitherof the drivingmembers during the continuous movement of the ack 1n one direction.

the opposite ends of which are keyed: a pair of pulleys 31 and '32. ofthe supporting frame 2 and adjacent to the levelingroll 1, a pair ofpulleys 33 and 3%. are journaled in alinement respectively with thepulleys 31 and The pulleys 33 and 3 1 are connected to. the drivepulleys and 34 and the clutches 38 are identical in To this end thedrive .pulley 25 is mounted upon. a transverse shaft 30 upon Upon thefront end;

theirconstruction and mode of operation,

it is onlv considered :necessary for a clear understanding of the-machine to describe one of the connections. One member 39 of'the clutch38 iskeyed to the inner end I of :a shaft 4O uponthe outer end of whichthe pulley 34 is fastened. The second member elof the clutch is formedintegrally with a sleeve 12 which is journaled in the frame 2 and whichforms a bearing for the shaft 10. A plurality of metallic disks s13 areheld between the clutch members and.

upon a relative'movement of the members to restrict the space, betweentherm'the disks 43 are pressed together, thus serving to lock the twomembers together and drive the sleeve4=2. The sleeve 42 is connected tothe leveling roll 1 by aflpair of intermeshing gears 44 and 45 which arekeyed to the sleeve 42 and rollsupportingshaft 46 re spectively.

In order to automatically'control the direction. of rotation of theleveling roll, means are. provided for simultaneously engaging anddisengaging the two clutches at predetermined intervals during thecontinuous operation of the machine. A path cam 50 is mounted upon thecrank shaft 10 and is capable of circumferential adjustment relativethereto by a plurality of bolt and slot connections 51. By adjusting thecam 50 in a circumferential direction, the reversal of the roll may bemade to take place at any desired point in the travel of the jack. Thecam 50 is operatively connected to one end of a lever 52 which ispivoted at 53 to the frame of the machine and which is connected at itsopposite end to an actuating rod 55. In order to form a yieldingconnection between the lever 52 and rod 55 a pair of springs 56 and 57are interposed between opposite faces of the lever and a pair of locknuts 58 and 59 respectively. The actuating rod 55 is connected to a rockshaft 60 by a-crank arm 61 so that upon an oscillation. of the lever 52about its pivotal point 53 the rock shaft60 is oscillated in itsbearings by the crank arm 61. A second and longer arm, 62 is keyed tothe rock shaft 60 and this second arm 62 is operatively connected to acrank arm 64 through a link 65. To enable the movement of the crank arm64 to be varied it is provided with a slot 63 supported in a bracket 69fastened to the machine frame and provided with a pair of downwardlyprojecting cars 70 in which the shaft 68 is journaled. In order to movethe shaft 68 longitudinally upon an oscillation of the arm 64, a finger70 projects from the shaft68 and engageswith a stationary pin 71, thuspreventing a rotation of the shaft in its bearings. The outer end of thefinger 70 is provided with a recess in which the pin is seated, as shownclearly in. Fig. 8, in order to prevent any lateral movement of thefinger relatively to the pin but to allow a longitudinal slidingmovement of the finger upon the pin. The pin 71 is detachably fastenedin a bracket 72 in which the shaft 60 is journaled, and in order toaccurately position the shaft 60 and pin 71 with relation to theirco6perating parts, the bracket 72 is detachably fastened to the machineframe and is universally adjustable thereon. This is accomplished byproviding a pair of transverse screws 73 which are threaded in thebracket and whichbear upon opposite sides of a cross member 74 and aclamp plate 75 which engages underneath the cross member 74 and isdetachably connected to the bracket 72 by'a plurality of adjustingscrews 76. A rock shaft 77 extends longitudinally of the supportingframe 2 and is journaled at its opposite endsin the frame 2 and thebracket .69. A short shaft 78 is journaled in the bracket 69 parallel tothe shaft 77 and is operatively connected to the latter by a pair oftoothed segments 79 and 80. The shaft 78 is oscillated in itsbearingsupon a longitudinal movement of the shaft 68 by a depending arm 81 whichis locked against rotation relatively to the shaft 7 8 and is providedwith a bifurcated portion 82 engaging a grooved collar 83 fastened tothe shaft 68. In order to adjust the arm 81 relatively to the shaft 78,an upstanding web 85 is keyed to the shaft and is engaged upon oppositesides by a pair of adjusting screws 86 which are threadedly mounted inears 87 formed upon the arm 81. I From an inspection of Fig. 9, it willbe noted that each of the clutch members 39.

is connected to an operating arm 88 pivotally mounted upon the rollsupporting frame at 90. The upper ends of the operat ing arms areconnected by a link indicated at 91 which is adjustable in length tovary the relative angular position of the arms j and adjust them toproperly actuate. the clutches 38. This adjustment is effected byforming the link of two members 92 and 93 which are connected togetherat their inner ends by a left and right screw-threaded member 94. Therock shaft 79 forms one of the pivotal connections and thus upon anoscillation of the shaft 77 the arms 88 are rocked simultaneously in thesame direction to engage one clutch and disengage the opposite clutch.

The operation of the machine is as follows: Assuming that the shoe to beleveled has been properly jacked'and that the various parts of, themachine have been adjusted to properly operate upon the particular shoe,the operating lever-'16 is then manipulated to move the jack-and shoebeneath the leveling roll. a When the machine is first started, it willbe assumed that the leveling roll is actuated from the drive pulley 25through the. crossed belt 35, thus rotating the roll in the direction ofmovement of point upon the sole substantiallyv coinci-.

dent with the ball line, the path cam .50 is arranged to, actuate thecontrol mechanism and the roll rides off the shoe before the di' Irection of movement of the jack isreversed.

Upon reversing the direction of movement of the jack, the roll and jackhave the same direction of movement and the roll is en abled to rideonto the heel end of :the shoe without injury to the same. The rollcontinues to rotate in this direction until approximately the same'pointis reached at which it was previously reversed, when the automaticcontrol is again actuated and the direction of rotation of the roll isnow reversed and is opposite to the direction of movement of the jack.With this mode. of operation, the sole is rubbed in opposite directionsover the ball. and shank portions and the entire sole is leveled withoutinjury to the projecting margin of the sole at the heel and toe.

While it is preferred to employ the specific construction andarrangement of parts shown and described, it will be understood thatthis construction and arrangement is not essential except so far asspecified in the claims, and may be changed or modified withoutdeparting from the broader features of the invention.
